Hi. I tried to find this information, but i'm totally lack of time. I'm going to buy a laptop (of course it will crunch BOINC). And now question: witch one will be better? (i mean higher RAC and/or lower power consumpion) T2500-core duo 2000MHz or T5500-core 2 duo 1660MHz? Or maybe one of Turion CPU's? |

Hi. I tried to find this information, but i'm totally lack of time. I checked with some people on our team running Conroe desktops @ 2Ghz to see wether or not I should replace my T2500 with a T7500, came to the conclusion that there was not going to be a huge difference in RAC between the 2 versions. Here's my laptop - Inspron E1705 with T2500 Of the cpu's you list, the T2500 would have the better RAC, IMO. Paul Team Starfire World BOINC IRC- irc//irc.teamstarfire.net:6667/team_starfire |

Hi. I tried to find this information, but i'm totally lack of time. The only major differences between a Core Duo and a Core 2 Duo are: a) higher FSB, b) 64bit CPU and c) SSSE3 (all these features are found in the Core 2 over the Core). Otherwise, they are exactly identical. The higher FSB should help crunching overall, and if you decide to use an optimized application, the SSSE3 would make the Core 2 a probable better choice. |

I agree on everything execpt for the part about the FSBs...at this point in time the hardware that is available for Core 2 Duo machines limits the FSB to 667MHz, however Q1 2007 the Santa Rosa chip will be available with higher clock cycles and the 800MHz FSB! Also, the Core 2 Duo (right now) is a better bang-for-the-buck as intel is trying to force the market to Core 2 Duos (see link for details) Here is an indepth look at the differences between Core 2 Duo and Core Duo http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2808&p=1 My recomendation: wait until Santa Rosa comes out! -citroja |

Only the mobile Core 2 Duos are stuck at 667MT/s FSB right now (and I see now that's what we're talking about). The desktop Core 2 Duos are 800MT/s and 1066MT/s FSBs. |

I knew this would be a right place to ask :). Looks like i shall buy a T7200 laptop, but i will buy T2500 (if nothing change). Strange that in Poland those laptops are 20% more expensive than T2500. Many thanks for answers. Greetings from Poland. |

Hi. I tried to find this information, but i'm totally lack of time. d) Core 2 has 128 bit SSE units (able to calculate two packaged 64 bit sse2 ops or 4 32 bit sse ops at once) |

d) Core 2 has 128 bit SSE units (able to calculate two packaged 64 bit sse2 ops or 4 32 bit sse ops at once) Thank you for pointing that out, but that's technically covered in "C) SSSE3..." as SSSE3 adds support for 128bit SSE registers. |

leave it to intel to confuse everyone and start a nice long debate :) Glad we could help Tito...let us know what you get! |

Ohh it will take little time, couse i'm going to buy it early of january. But for sure i will inform You (after some calculation done). |

If you see a good offer for a T7200, then go for that one. Regards Hans |
